They look so simple, albeit a little ugly – those Round Burners that, at the turn of a knob, burst into a ring of flames for you to cook, boil or heat up whatever you care to put above the flames – put the knob in different positions and the flame goes from extremely fierce to almost non-existent. They are just another of modern life’s daily features that are simply “there” to be used without any thought to how they actually work.
Cooking On Gas
These days, we have a choice of gas to burn in our stoves, grills and ranges; cooking gas can be natural gas (sometimes, piped to our home) or commercially available bottled gases such as LPG, propane or butane (also available in bulk supply for your own storage tank). Whichever gas we choose, it has to be mixed with a precisely controlled amount of air if it is to burn efficiently with maximum heat potential and no messy soot. An important part of any gas burner is the device that sets the air to fuel ratio and, it should be noted, that the ratio is different for different types of gas.
Getting Out Of The Kitchen
Gas is used for heating in many non-domestic activities; some of them (such as commercial bakeries, restaurants, etc) are, effectively our domestic kitchen on a much larger scale and they will use the same sort of Round Burner that we have in our homes. Other industries also require volumes of hot liquid for their business and will opt for gas as their heating fuel for such as hot rinse or cleaning tanks, heat exchangers, etc – even, micro-brewing. The Round Burner they use will probably be slightly different from the domestic one and is often referred to as a “radial burner”; it will also have a more sophisticated control for the air to gas mixture.
Obviously, industrial burners will tend to be larger than those for domestic use and there are several other types of Round Burner in industrial use for heating tanks, vats, furnaces, etc. They can also be used for quickly heating up a casting pot of low melt point metal such as lead or pewter. Circular ring burners are popular in the food processing sector as well as providing instant heat to the huge woks seen in many a Chinese restaurant. Other applications use a Round Burner known as an “urn burner” – choice is decided by how much heat is required and over what shape an area it is needed.
